New findings about neuropathological outcomes in the PKU mouse throughout lifespan.

Phenylketonuria (PKU, OMIM 261600) is a genetic disorder caused by a deficiency of the hepatic enzyme phenylalanine hydroxylase (PAH). If left untreated, PKU leads to systemic phenylalanine (Phe) accumulation, which can result in irreversible brain damage and intellectual disabilities. In the last 60 years, early and strict dietary restriction of phenylalanine (Phe) intake proved to prevent the severe clinical phenotype of untreated PKU.

Developing and testing an Arduino-based microcurrent stimulator to mimic marine electric pollution on benthos.

The lack of economic funds commonly represents a limiting factor in scientific research and prevents scientists from developing brilliant ideas. Indeed, a new project may involve using appropriate scientific instruments and concurrently dealing with the costs before pursuing new research fields. The innovative concept of investigating the effects of electric fields, as a simulation of marine electrical pollution, on benthic organisms such as foraminifera (marine protozoa) has been recently explored by our research group.

Selectivity of herbicides used in corn on Crotalaria ochroleuca G. Don.

In the cropping systems that integrate the corn crop, the insertion of Crotalaria ochroleuca G. Don is predominantly intercropped. In this context, there is a need to observe herbicides that present selectivity for this sunn hemp species.

5HT1AR-FGFR1 Heteroreceptor Complexes Differently Modulate GIRK Currents in the Dorsal Hippocampus and the Dorsal Raphe Serotonin Nucleus of Control Rats and of a Genetic Rat Model of Depression.

The midbrain raphe serotonin (5HT) neurons provide the main ascending serotonergic projection to the forebrain, including hippocampus, which has a role in the pathophysiology of depressive disorder. Serotonin 5HT1A receptor (R) activation at the soma-dendritic level of serotonergic raphe neurons and glutamatergic hippocampal pyramidal neurons leads to a decrease in neuronal firing by activation of G protein-coupled inwardly-rectifying potassium (GIRK) channels. In this raphe-hippocampal serotonin neuron system, the existence of 5HT1AR-FGFR1 heteroreceptor complexes has been proven, but the functional receptor-receptor interactions in the heterocomplexes have only been investigated in CA1 pyramidal neurons of control (SD) rats.
